Overview

Introducing the 2012 KTM 50 SX Mini, a pint-sized powerhouse designed specifically for young riders eager to dive into the world of motocross. As a member of KTM's prestigious SX lineup, this minibike is engineered to deliver an exhilarating experience on the track. Its lightweight design and performance-driven features make it an ideal entry-level motorcycle for budding racers, ensuring that they can develop their skills in a safe and controlled environment. With its striking orange, black, and white color scheme, the 50 SX Mini stands out, embodying the spirit of KTM's commitment to performance and style. At the heart of the 50 SX Mini is a potent 49cc single-cylinder, two-stroke engine that promises spirited performance. The engine's bore and stroke measurements of 39.5 x 40.0 mm ensure a responsive throttle and a thrilling rush of power that will inspire confidence in young riders. Coupled with a liquid cooling system, this engine remains efficient even during intense rides. The bike features a simple 1-speed gearbox with a centrifugal automatic clutch, allowing young riders to focus on their skills without the distraction of manual gear changes. With a lightweight frame tipping the scales at just 40.5 kg (89.3 pounds), the KTM 50 SX Mini is agile and easy to maneuver, making it perfect for navigating tight corners and jumps on the track. KTM has outfitted the 50 SX Mini with premium components that enhance both performance and safety. The lightweight chrome molybdenum steel frame is not only durable but also powder-coated for added resilience against the rigors of motocross. The WP Suspension USD 35 in the front and WP Suspension 3614 BAEM in the rear provide excellent handling and comfort, with generous travel of 100 mm (3.9 inches) in the front and an impressive 171 mm (6.7 inches) in the rear. Braking is equally impressive, featuring a single disc setup with a four-pot caliper in the front and a two-pot caliper in the rear, ensuring reliable stopping power. With a ground clearance of 184 mm (7.2 inches) and a seat height of 558 mm (22 inches), this minibike is perfectly tailored for younger riders, giving them the confidence they need to tackle any terrain. **
